The drain port 8 is provided at the same position. Each rail 31, 32, 33 and each auxiliary wall 4
1, 42 project at substantially equal intervals, and
It is formed at the same height as 2.

The third embodiment of the sill flat sash according to the present invention will be described in terms of differences from the first embodiment. As shown in FIG. 8, the rail lower frame member 2 is slightly directed from the indoor wall 20 to the outside. The first rail 31, the second rail 32, and the third rail 33 are sequentially provided in parallel on the upper side of the lower frame member 2, and the first auxiliary wall 41 is provided between the first rail 31 and the second rail 32. Are provided in parallel. In the first and third embodiments, the first rail 31 and the second rail 32 are sliding rails, and the third rail 33 is a knitted door rail.

The running water gutter 6 provided below the support wall 21 includes an indoor wall 20, a support wall 21, a front wall 61 which is inclined downward from the outside of the support wall 21 to the outside of the room, a front wall 61 and the indoor wall. 2
0 and a bottom wall 62 continuous between the lower portions of
Numeral 1 is inclined downward from the outdoor side of the second rail 32 to receive rainwater W accumulated on the indoor side from the second rail 32 and to reinforce the support wall 21.

The shaft support 9 is integrally formed on the upper part of the outside of the front wall 61 of the running water gutter.
9 is provided in the longitudinal direction of the lower frame member 2 and has substantially the same shape as the screw pocket 23 provided below the support wall 21 and the running water gutter 6. As shown in FIG. 4, the opening / closing plate 5 is provided with a shaft portion 51 to be inserted into the shaft support 9 on the left and right of a shielding plate 52 slightly larger than the drain port 8, and the shielding plate 52 is positioned outside the front wall 61. ,
The shaft portion 51 is inserted into the shaft support portion 9 so as to be able to swing around the shaft support portion 9 into and out of the room. Usually, the shaft portion 51 comes into contact with the outside of the front wall 61 by its own weight, and the drain port 8 is closed.

Since the sill flat sash of the present invention has the above-described structure, the rainwater W that collects on the indoor side from the second rail 32 is provided.
First, after flowing into the flowing water gutter 6 from the first drainage hole 7 of the support wall 21 and accumulating to some extent in the flowing water gutter 6, the water pressure H pushes the opening / closing plate 5 closing the drainage opening 8 to the outside of the room to drain the water. Mouth 8
The rainwater W that has flowed out from the outside and sprayed to the outside of the room from the second rail 32 flows directly to the outside from the second drain hole 17. Even if the wind and rain is sprayed toward the drain port 8, the wind and rain is sprayed onto the opening / closing plate 5 located outside the room from the drain port 8, pressing the opening / closing plate 5 toward the drain port 8 and closing the drain port 8 with the opening / closing plate 5. Therefore, there is no backflow in the running water gutter 6.

The openable and closable plate 5 which is inserted into the shaft support 9 and can be swung is opened and closed by a difference between a water pressure H of the rainwater W accumulated in the running water gutter 6 and an external pressure P for pressing the open / close plate 5. That is, the water pressure H of the rainwater W accumulated in the running water gutter 6 is reduced by the external pressure P of the opening / closing plate 5 closing the drain port 8 (the weight of the opening / closing plate 5,
When the air pressure is higher than the wind pressure blown onto the opening / closing plate 5 from the second drain hole 17, the opening / closing plate 5 that has closed the drain port 8 is pushed outward as shown in FIGS. Leaked to Conversely, when the water pressure H of the rainwater W collected in the running water gutter 6 becomes lower than the external pressure P of the opening / closing plate 5, the opening / closing plate 5 is pressed toward the front wall 61 of the running water gutter 6 by the external pressure P and provided on the front wall 61. The drain port 8 is closed. Since the rainwater W flowing down from the second drain hole 17 presses the opening / closing plate 5 toward the drain port 8, as the amount of drainage from the second drain hole 17 increases, the drainage increases the closing pressure of the opening / closing plate 5.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Each rail 31, 32, 33 and each auxiliary wall 41,
If the longitudinal end of 42 is notched, drainage and cleaning become easier, and if the bottom wall 62 of the running water gutter 6 is inclined downward toward the outside of the room, the drainage from the running water gutter 6 is also reduced. It becomes even easier. When the drain valve V is inserted into the first drain hole 7 as shown in FIG. 10, the blowing of wind and rain from the running water gutter 6 can be further prevented.

[0015]

The sill flat sash according to the present invention has the same structure as described above, and has the following effects. The sill surface flat sash according to claim 1, wherein a first auxiliary wall is provided between the first rail and the second rail of the lower frame material, and a second auxiliary wall is provided outside the third rail. In addition, since the vertical interval between the wheels is reduced and the rails and the auxiliary wall are formed at substantially the same height, the wheelchair wheels can easily enter and exit without falling down, and no unnecessary load is applied to the rails. In addition, part of the rainwater that collects on the rail support wall of the lower frame material is drained from the first drain hole into the running water gutter, and the opening / closing plate that covers the drain port is pushed out from the drain port to drain to the outside. Since a part is drained directly to the outside from the second drain hole, rainwater can be efficiently drained even with a lower frame member having a large number of rails and auxiliary walls erected. Moreover, as the external pressure blown toward the drain increases, the closing pressure of the open / close plate increases,
The blowing of wind and rain into the running water gutter from the drain outlet is reduced.
As a result, high watertightness is obtained. In addition, since the position of the rainwater is different from the position of the drain port and the first drain hole, even if the rainstorm blows into the drain port from the outside, it does not blow up into the room from the support wall and faces the drain port. Since the closing pressure of the opening / closing plate increases as the amount of drainage from the second drain hole increases, the amount of wind and rain blown into the running water gutter from the drain port decreases.

In the sill flat sash according to the second aspect, in addition to the effect of the first aspect, since there is no step with the indoor floor plate and there is no step with the approach of a balcony or the like provided on the outdoor side, the wheelchair can be used. Getting in and out is easier.
